In this paper, we demonstrate how a systems of equation that is in the form Ax=b are transformed into a form A-1x=b. This is achieved by obtaining the matrix A and its inverse (A-1). When this has been done, the sender sends the systems of equation in the form Cx=b (where C= A-1), if an intruder decrypts the systems Cx=b, he/she will not be able to recover the plaintext; except of course he/she have an advance knowledge that the system being decrypted is A-1x=b and not Ax=b
